Mystery writer and amateur detective Jessica Fletcher - a down-to-earth, middle-aged widow - ferrets out the criminals in idyllic Cabot Cove, Maine, which apparently is the murder capital of the United States for the show's 12-season run. Though while traveling, she uncovers a fair number of killers as well.

An art gallery owner is stabbed to death with a sculpture belonging to Jessica's friend (Loretta Swit).

Jessica attempts to clear the name of a Cabot Cove fisherman who is suspected of murdering a Chicago hit man.

Jessica refuses to believe that the editor of her latest book has committed suicide and is determined to find out the truth.

Infrared cameras seem to prove Jessica's writing student is guilty of killing his abusive stepfather.
